Answer:
- Bill was swimming for 30 minutes, 3 days per week and recently increased that to 45 minutes, 3 days per week: D. Duration
- Sonya was participating in one aerobics class per week and recently increased that to two aerobics classes per week: C. Frequency
- Erin was walking on the treadmill at a rate of 3 miles per hour for 60 minutes and recently was able to increase her rate to 4 miles per hour for 60 minutes: B. Intensity
- Chris used to do 30 minutes of cardio at 50% of his max heart rate 2 days per week and has gradually increased his performance such that now he is exercising for 60 minutes at 80% of his max heart rate 4 days per week: A. Progression
Explanation:
Duration refers to the amount of time accumulated in a specific physical exercise program (in this case, swimming), which is measured in a given time unit like minutes or hours. Moreover, the frequency can be defined as the occurrence/practice of a given physical activity (in this case, aerobics classes) that is repeated at specific intervals of time. Intensity refers to the speed/workload of a given exercise or training session. Intensity can be divided into two forms: 1-absolute intensity, which is expressed as a percentage of an individual's maximal aerobic capacity, and 2-relative intensity, which is the percent of one repetition maximum for each exercise. Finally, progression is the rate of increase of the intensity, frequency and duration of physical activity from the initial to the maintenance stages (the progression stages include initial, improvement and maintenance stages). Progression is dependent on diverse factors inherent to the individual, i.e., the tolerance to exertion, the objective of the physical exercise, and his/her age.

Explanation:
Answer:
Cholinergic systems which are an organisation of nerve cells that uses acetylcholine in communicating nerve impulses are found everywhere in the human central nervous system.
It is speculated that they are crucial to learning, attention, memory, speaking and carrying out purposive movements. This is because of their high density in the thalamus, striatum, limbic system, and neocortex.
Cholinergic agents are biochemical compounds which produce the same effects as acetylcholine and/or butyrylcholine.
Studies show that the parasympathetic nervous system (which comprise of the rest and digest system and conserves energy decelerating the heart rate, accelerating intestinal and gland activity etc) uses acetylcholine to a great extent to communicate its messages and is said to be mostly cholinergic.

Answer:
a. Mitochondria
Explanation:
Mitochondria, the so-called "powerhouses" of cells, are unusual organelles in that they are surrounded by a double membrane and retain their own small genome.
Answer:
The lower portion of the labia
Explanation: The area of the Bartholin glands in the lower portion of the labia may be palpated between the thumb and index fingers of the left hand by placing the index finger just inside the vaginal introitus. Ordinarily, normal Bartholin glands cannot be felt and are not tender.
